Strange vibration
I'm getting a strange vibration sound from the rear, only at a certain rpm in 1st, or maybe it's just most noticeable at that time. If I run through first normally into second, all sounds normal. It's when I linger in first between 3k - 5k rpms, I am hearing it. Any ideas??

Wheel bearings come to mind.
When I'm just coasting down the road mine make a tad bit of noise. Makes me glad I've fabricated a puller and press that get the job done super fast. Tried it out on Odurandina's 968 / LS7 a few months ago. Will not be long until I do my own.
Or it could be your shifter linkage, but I think that is only on the G50 cars.

I actually found this thread on another forum, which more accurately describes what I'm hearing. This make sense given a 915 tranny? I've read the G50 differs in the linkage or something to that extent. Here's the quote
"mine has just developed a 'whine' in 3rd - it sounded more like holding a coin against a spinning disc brake/flywheel thingy as it turned (ie it was a metalic grindy/scorey noise) but it was only in 3rd, not 2nd or 4th ? Turned out to be a perished bush/washer thingy (im so technical!) in gear shaft linkage, making the shaft press rub against the tunnel side" end quote

I really only hear the noise under load, which is in lingering in the powerband in first, like between 3-5k. Mechanic / owner of shop is going to "live" w/ car for this week. He's going to take it to and from home / work and try to pinpoint this noise and also the idling issue I've been having.
